SPRlNG-SHACKLE FOR VEHICLES.

SPECIFICATION forming part of Letters Patent No. 763,126, dated. June21, 1904.

Application filed November 23, 1903. Serial No. 182,234. No model.)

To all whom it may concern:

Be it known that LHENRY (lSWAN, of Cleveland, Cuyahoga county, Ohio,have invented a new and useful Spring-Shackle for Vehicles, of which thefollowing is a full, clear, and exact description, reference being hadto the accompanying drawing, forming part of this specification, inwhich the figure is a top plan view, partly broken away, showing myimproved shackle.

My invention relates to the spring-shackles employed in connection withthe springs of vehicles, and is designed to cheapen and improve theirconstruction. Heretofore these shackles have usually been made ofwroughtiron or of cast metal in the form of my Patent No. 597,865, ofJanuary 25, 1898. The construction shown in this patent while cheaperand simpler than the wrought-iron shackle is formed of two separateparts, with a joint along the intermediate part of the shackle-body.

My present invention further simplifies and improves the constructionand enables the shackle to be cast in one piece.

In the preferred form shown in the drawing, 2 represents the usual boXor hearing for the equalizer-rod, this bearing lying on the top of aperch and axle of the ordinary side springgear. The shackle 3 is cast inone integral piece of U shape and is formed at one side with aprojecting hub or sleeve 4, having a hole, preferably of cylindricalform, with its end portion flattened and curved, as shown at 5, over thecentral portion of the shackleopening.

The equalizer-rod 6 is cut away on the under side at its end and is thendriven or pressed into the shackle, with its cut-away end fitting on thecurved flat wall 5 in the hole in the shackle-sleeve. To preventwithdrawal of the shaft or equalizer-rod, a rivet 7 is passedbe of anydesired form.

The shackle operates in the usual manner, the equalizing-rods performingtheir usual functions.

The advantages of my invention result from the cheapness and simplicityof the device, its formation in one piece, and its consequent strength.1

Variations may be made in the form and. size of the shackle and the rodconnection without departing from my invention.

I claim 1. In a spring-shackle, a hub with integral legs projecting atright angles thereto and arranged to receive the spring between theirouter ends, the hub having a hole or recess with a closed end and anangular portion, and an equalizing-rod having an angular end portion andsecured within the hole; substantially as described.

2. A spring-shackle cast in one piece with a hole or recess having aflat wall at one side of its inner end, an equalizing-rod arranged tofit in the recess with a flattened face arranged to fit the wall ofthehole, and a rivet securing the rod in position; substantially asdescribed.

In testimony whereof I have hereunto set my hand.

HENRY C. SWAN.
